I wrote more about this in another comment ("Postmortem"), as I developed a similar idea from Mid 2022 to early 2023, but made different decisions. OpenAI had a serious focus on this that did see adoption; as early as Spring 2021

Beware that most 2020-2021 OpenAI startups haven't survived to today, especially since ChatGPT allowed free use of most B2C use cases (article writing, paraphrasing, etc). I posted a brief postmortem of my experience from 2021 to 2023

Here's a post-mortem and the true history of this tooling approach and being a first mover, or not... Pre 2021: Useful semantic search widely deployed, used for recommendations for sales. OpenAI has an answers endpoint specifically for

Specifically, we used semantic similarity for shuffled answers (so they are close and not too easy), completely shuffled answers, and AI-generated distractors. We are now going to choose the most popular default (based on retention during A

Really good points on the angle there, thank you. And important point that it shouldn't necessarily come from you! (that's what's worked better for us everywhere but ProductHunt, reflecting on it)

Thank you, this bug has been fixed. We recently changed from shuffled distractors to Ai-generated distractors, but as you identified, such a bug could occur.

A flipside effect to this is advertising and PPC which has trended up so high overtime, especially in education. Strategies viable in 2019 are largely useless to bootstrapped businesses in 2023: the costs of ads even to acquire customers wi

Yes, that's correct. Then OpenAI bills you around the end of the month so you have some leeway of credit. You can use local embeddings, such as sentence transformer models, too, to save on embeddings (and maintain embeddings you can mo

It's also the norm at small German universities and, till recently, many larger ones. It has not harmed German students and I believe puts Germany in a better position right now.

It's an unusual 2 year or so window where this has been fairly possible, and still not realised or accepted by instructors. It's just too outside the current paradigm. It has coincided with students not having to do exams during C

Thank you. That's a good point, we should experiment soon. Originally, we had free text input, but too many students quit with that difficulty. Maybe a mix or new concept can fit well here. Edit: Re-reading your comment, perhaps it

Request a GPU allocation, and use it, request again, etc. Unfortunately it has been like this since around 2020/2021. It's sensible on AWS' side I guess. If you really need them, you won't get credits but there are GPU-s

It's mentioned in the article, but LoRA or RAG will enable this. Phind is getting awfully close to this point already really. Integrating new knowledge isn't a bottleneck like we know from expert systems, I think it just hasn'

You're right and this is why they didn't heavily use BERT(in the full sense), arguably the game-changing NLP model of the 10s. They couldn't justify bringing the cost per search up.

ChatGPT is expensive, but take Chegg for example. They hire thousands of people to support a system based on human-produced content delivered in the right time threshold to be worth paying for. Now ChatGPT is a lower-risk way (less likely t

Langchain --> query_with_sources function (semantic search context) If you finetune, you'll get mostly the style and sometimes worse factual performance. Source through semantic search context/RAG is a better approach. Source:

Thing is for things to take off, what is often key is retention. And retention stats relative to the normal/non-AI way of doing it (e.g. learning a wikipedia page) with these models for most use cases have looked like: GPT-2: 2% GPT-3:

This pretty heavily assumes that you can't learn programming by paper or on a shared school computer (quite widely available in the UK/US for a couple of decades now), which itself reveals a bias in your mindset here, tbh.

A great deal of advice here is going to push you in the direction of VC funded startups and the Lean Startup style approach. You might want to go that way, but as you said "build", not "sell", you may value the approach
